Midterm election's biggest campaign controversies: The top 9 of 2018

From a senator outing sexual assault survivors to a campaign manager allegedly assaulted by a tracker, the 2018 midterm elections have been rife with controversy.

As Election Day looms, read on for a look at nine of the most controversial moments of the 2018 midterms.

Less than a month before the election, Sen. Heidi Heitkamp, D-N.D., had to apologize after her campaign publicly identified domestic and sexual abuse survivors in an ad without getting permission from several.

The ad, placed in multiple North Dakota newspapers, was an open letter in opposition to GOP opponent Rep. Kevin Cramer. It criticized comments he made before Justice Brett Kavanaugh was confirmed to the Supreme Court. It was signed by more than 125 people, although some were just initials.

Keeley Beck said her name was printed in the ad without her permission.
